The free agent frenzy is starting to wind down, as the big names have all been spoken for and the league’s general managers are now picking through the scraps.

But that doesn’t mean you can’t find good players out there. Some of the best free agent deals have come late in the summer after the fanfare has long since departed — witness, for instance, the impact of afterthought free agents like San Antonio’s Fabricio Oberto and Golden State’s Matt Barnes in last year’s playoffs.

Thus, digging through the scrap heap can pay dividends. And while the Nets and Knicks seem mostly done with their free agent shopping, in a couple of cases one can see opportunity for the locals to upgrade the roster. With that in mind, let’s take a look at the leftovers and see what morsels look tasty:

Anderson Varejao, Cleveland – Easily the most coveted free agent remaining, Varejao is in a bind because he’s a restricted free agent, meaning the Cavaliers can match any offer. With all the teams with cap space done shopping, Cleveland is essentially bidding against itself at this point. Expect Varejao to remain a Cav, but he might take a one-year deal and go back on the market next year.

Ruben Patterson, Milwaukee – Patterson quietly played his butt off for the dilapidated Bucks last year. While nobody is expecting a repeat on that level, his high-energy game would be a great fit in the Meadowlands. Weirdly, nobody seems terribly intent on pursuing him in spite of his undeniably impressive results last season, so somebody is going to end up with a bargain.

Ime Udoka, Portland – The Blazers’ defensive ace is exactly the kind of player the Knicks need – he works hard, battles on defense, and he doesn’t need the ball to be effective. Too bad they cut him a year ago. Instead look for Udoka to take a payday as a role player for a contender, with San Antonio in the driver’s seat.

Chris Webber, Detroit – The declining big man still has enough skill to overcome his increasing physical limitations, especially if he has teammates who can cover his back on D. Speaking of D, it seems he’ll end up in either Detroit or Dallas. Isiah Thomas is reportedly a fan too, but the Knicks already are overstaffed.

Matt Barnes, Golden State – The Knicks cut Barnes, too … but they kept Jerome James. Now he’s shopping for a deal after a big year for the Warriors, but getting surprisingly few nibbles. His price tag is probably too high for either of the local squads though.

Brevin Knight, Charlotte – If the Nets have to include Marcus Williams in a trade for Jermaine O’Neal, their first call afterward should be to Knight. He’s a Jersey boy, and his uptempo style would keep the running game going even when Jason Kidd checks out. He’s also far and away the best point guard left on the market, so the increasingly desperate Heat may nab him first.

Actually, Knight would be great with the Knicks too — he could teach Zach Randolph and Jamal Crawford what a pass is — but presumably the ‘Bockers’ roster overload prevents that from happening.

Earl Boykins, Milwaukee – Though he is essentially a 5-foot-5-inch shooting guard, Boykins’s high-octane play has helped him become one of the league’s top sixth men. He shoots too much and passes too little, but on the right team he can be a force of nature.

Charlie Bell, Milwaukee – An underrated reserve who knocks down shots and plays dogged D, Bell would be a nice piece to plug into Jersey’s rotation. Alas, he’s probably out of the Nets’ price range, and probably returning to the Bucks in any event.

Mickael Pietrus, Golden State – A talented player whose mental game seems miles behind his physical skills, Pietrus could be had in a sign-and-trade with a good enough offer. The Knicks don’t really need a guy like this, but the Nets do – he’s a knucklehead, but at his best Pietrus knocks down 3s and defends like crazy. Thus, one wonders if they could do a sign-and-trade that donated Jason Collins to Golden State. Just thinking out loud here.

Chuck Hayes, Houston – Offensively limited, but an outstanding defender and rebounder, Hayes has value on a halfcourt team. Nobody has done much pursuing though, as it appears likely he’ll return to the Rockets.

Sasha Pavlovic, Cleveland – The much-improved wing is another guy that would look pretty good in a Nets uniform … and another guy that won’t be going anywhere, since he’s a restricted free agent.

Andray Blatche, Washington – The rangy 6-foot-11-inch forward has scouts salivating, but his limited court time the past couple years has prevented other clubs from stepping up with strong offers. New Jersey reportedly had interest but quickly went in another direction; probably smart since he’s restricted and the Wizards would have matched their offer.

James Posey, Miami – A key cog in Miami’s title run, Posey is in clear decline (like many of his teammates) and he may have to take far less money than he’d expected. If he gets paid, it will be on reputation and not performance.

Desmond Mason, New Orleans – The athletic wingman is reportedly close to a deal with Milwaukee, where he played two years ago. Since then, though, his offensive game has totally fallen apart, so this could be money badly spent.

Jannero Pargo, New Orleans – Can’t decide what’s more distressing – that the Nets are interested in this one-dimensional gunner, or that he’s reportedly out of their price range.

Melvin Ely, San Antonio – Anyone else a little surprised that the Nets spent two years trying to trade for this guy, and yet now that he’s a free agent we’ve heard absolutely nada about Jersey pursuing him?

P.J. Brown, Chicago – Exactly the kind of solid pro that both the Nets and Knicks could use in their frontcourt, but don’t expect him to show up in a local uniform. He’s either hanging up his sneaks or joining a contender — don’t be shocked if he becomes a Maverick.
